With the help of diagrams, list the
supporting members of the hull
frames.

FRAMING:


The hull must have a framing system to
support it because the hull itself, like a
bridge, spans a fluid substance.


Whereas a bridge spans air, a hull spans
water, and while water is more dense, it is
still a fluid and offers lesser means of
support than solid ground.


Unless the hull has an adequate system of
framing and girders to span the
unsupported sections, like a bridge it will
buckle and collapse.


Frames

serve the purpose of stiffening
panels between bulkheads and stringers.
Obviously, if a panel is flexing too much,
additional framing would prevent that
condition.


Some builders scrimp on frames because
frames create additional detail work and
adds more to labor cost. But since frames
are an integral part of ship building they
must be given utmost importance

The stiffening is generally provided by :

SECONDARY

supporting
members.

STERN PLATING

LONGITUDINALS












BOTTOM TRANSVERSE
: The first part at the
bottom Is known as Bottom transverse and is
represented by a solid floor with double bottom
construction. The height of the bottom transverse
is similar to that of the centreline girder.


WEB FRAME
: The second part on the side is
known as web frame. The depth of the side web
frame is about 0.125 times the vertical distance
from the tank top to the deck above ,eg if this
vertical line is 10 mts ,the depth of the web wil be
1.25 mts.


DECK TRANSVERSE
: The third part on the
deck is known as deck transverse. The depth of
this varies dependant on the span between the
supporting girders or bulkheads,or between
girder and side frame
















Transverse Rings

STRUCTURAL MEMBERS













LONGITUDINALS:

All the secondary supporting
members that are fitted in the longitudinal
direction are known as ‘
Longitudinals
’.


HOLD FRAMES
:

In the transverse framing
system,the hold frames are fitted transversely.
The side members are known as the
hold
frame

or
main frame.


DECK BEAMS
: I
n the transverse framing
system,the deck member is known as the deck
beam. Longitudinal deck girders support the
transverse deck beams.
